FRIEND lY. SMITH, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THE EEASLEY SUPPLY COMPANY, OF NEIV YORK, N. Y.

REGISTERI'NGHWHEEL.

SPECIFICATION forming part of Letters Patent No. 406,312, dated July 2, 1889.

Application filed October 8, 1888. Serial No. 287,494. (No model.)

To all whom it may concern.-

Be it known that I, FRIEND lV. SMITH, a citizen of thel United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Registering- IVheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in the construction of wheels-such as are used in registering--and has for its object to so construct said wheels that they shall be exceedingly light, while at the same time a facing and background of celluloid or other analogous material may be utilized for carrying the numbers Without any danger of chipping or breaking'.

Vith these ends in view my invention consists in the details of construction and combination of elements, such as will be hereinafter fully set forth, and then specilically designated by the claims.

In the accompanying drawings, Figure l is a sectional elevation of a register-lock embodying my improvement; Fig. 2, a detail perspective of my improved wheel shown in vsaid lock; Fig. 3, a vertical section of said wheel without the guide-flange for the .floatwheels shown in said lock; Fig. 4, a view similar to Fig. 3, but showing the notched side face-plate extended above the celluloid facing, the latter being perfectly plain and without notches; and Fig. 5, a central vertical section of a wheel, showing the celluloid ring eoniined between the side face-plates.

Similar let-ters denote like parts inthe several figures.

In order to afford a practical illustration of the use of my wheel, I have shown' the same in connection with an ordinary registerlock, but I will enter into no description of said lock, as the latter forms no part of my present invention. In the construction of registering-wheels the use of celluloid or other analogous light material is very advantageous, in that the numbers may be readily impressed therein, while the celluloid itself is exceedingly light and alfords an excellent background for distinguishing said numbers.

Celluloid wheels have heretofore been used in numberingand similar machines, but they are liable to be imperfect, and in use they often become chipped and broken, thus effeetually subverting their utility.

My invention contemplates the construction of a wheel which has all the advantages of a celluloid wheel, and also obviates all danger of breaking.

A is a metal bushing, and B a celluloid wheel shrunk thereon. C is a met-allie faceplate rigid with said bushing and extending against one side of said wheel. D are notches in the periphery of said plate, which afford graspingshoulders for the pawl which acts to rotate the wheel.

Vhen my improvement is used in the connection shown at.- Fig. l, notchesE are forlned within the periphery of the celluloid Wheel for the accommodation of the operating-pawls F, which project from the float-wheels G, but these notches are wider than the notches D, so that it will be clearly seen that the force necessary to turn the wheel is exerted direct-ly against the face-plate and not against the wheel; also any sudden concussion or rough manipulation of the machine embodying my wheel is sustained entirely by the metallic face-plate.

In Figs. l and 2 I have shown a guide-flange Il on the bushing in order to afford a proper guideway I for the float-wheels G; but said iiange is merely adj unctive to this particular use of my improvement, and I do not wish to be circumscribed thereby, the gist of my invention resting in the broad idea of the protection of the celluloid wheel by the notched face-plate. If desired, said plate may extend on both sides of the wheel, as shown at Fig. 5; but this is unnecessary except when the wheel is to be operated from both sides.

Ordinarily the operating pawl or pawls need extend only within the notches D, and it is therefore immaterial whether the wheel is notched or not.

In Fig. 3 I have shown the bushing without the flange, since the latter would be dispensed with in very many instances, and in Fig. 4 I
